For the Bluetooth devices to communicate, they must share the same profile. Consult your Bluetooth device manual to find the profile required for the devices to communicate.

Verify that the Bluetooth devices are switched on.

In order for the Bluetooth devices to communicate, both of the devices must have Bluetooth functionality turned on.

Verify that both Bluetooth devices are paired.

For security reasons, both Bluetooth devices need to be paired before they can transfer data. After the devices are paired, encrypted data can be sent through the Bluetooth connection. Once the paired Bluetooth network is encrypted, only Bluetooth devices that have authorization will be able to communicate with one another.

Bluetooth is a low-range network used for linking personal unwired devices like cell phones, PDAs, and other platforms. Bluetooth provides a peer-to-peer network of devices called wireless personal area network (WPAN) as opposed to wireless local area network (WLAN) technologies like 802.11 which are focused on connecting a device to a traditional network. Additionally, it is optimized for low power consumption and shorter ranges than wireless LANs, and is geared more for mobile personal devices. The average range of a Bluetooth network is around 30 feet with a data transfer rate of 1Mbps, which is three to eight times the average speed of parallel and serial ports.

Press Fn+F5 to open the Wireless Radio Control and turn on the Integrated Bluetooth features. Whenever you start the computer or resume operation after it has been in standby or hibernation mode, you must turn on the Bluetooth features.Note: Select ThinkPad models include a Bluetooth button.

When any serial-based connection is established, an inactivity timer starts. If no application opens the port, the connection is ended automatically. This is a normal characteristic of the serial-based connection and is not a defect. If you need the Bluetooth serial port, just reconnect it.

You cannot use Hyperterminal through the Bluetooth serial port on Microsoft Windows 98SE. On these operating systems the Bluetooth serial port service uses one of the COM5 or above COM ports and Hyperterminal uses one of the ports between COM1 and COM4.

Cannot turn on Bluetooth after resuming computer from suspend or hibernation

Turn on the Bluetooth with Fn+F5 Wireless Radio Control before going into suspend or hibernation mode. If the Bluetooth is turned off before going into suspend or hibernation mode, the Windows operating system takes some time to enable the Bluetooth as a USB device.Note: Select ThinkPad models include a Bluetooth button.
